Shorebird fall migration is more than half over

Today is August 24.   It's hard to believe that 60% of the fall shorebird southward migration, from Arctic Canada, has already occurred, but it has.   According to Ron Pittaway, of the Ontario Field Ornithologists, The migration begins back in late June, with Lesser Yellowlegs (pictured above) and Least Sandpipers heading south.   By Mid-August, nine more common species of shorebirds have finished their southern migration through Ontario (Greater Yellowlegs/Solitary Sandpiper/Stilt Sandpiper/ Short-billed Dowitcher/ Red Knot/ Sanderling/ Semipalmated Sandpiper/ Baird's Sandpiper and Ruddy Turnstone.   Between late August and mid-September, seven more shorebirds have made the migration (Semipalmated Plover/ White-rumped Sandpiper/ Pectoral Sandpiper/Long-billed Dowitcher/Black-bellied Plover/American Golden Plover and the Dunlin.   The Dunlin's migration is late and short: mid-September to Early November.   Many other shorebirds pass through Ontario and  rarely nest here, so are excluded from this list.   Most birds that fail to nest north of Hudson Bay are not on this list also.   Tjhey all have a long way to go after Ontario also.   My visit to the Holland Landing sewage lagoons today turned up a dozen Lesser Yellowlegs and one Spotted Sandpiper.
